Debunking the Top 5 Myths About Solar Street Lights 

In Solar Lighting Roadway and Streets, Streetlighting by Fonroche Lighting

Why Solar Myths Still Exist 

Even as cities across the U.S. shift toward cleaner, smarter infrastructure, solar street lighting is still held back by outdated misconceptions. Questions like “Does it work in the winter?” or “Is it bright enough for a real road?” reflect concerns rooted in early-generation solar products—or low-cost imports that don’t meet U.S. standards. 

The truth? Today’s solar lighting technology is engineered for reliability, safety, and urban performance. Systems like Fonroche SmartLights are already lighting major cities, dense neighborhoods, and transportation corridors with no grid connection—and no compromise on quality. Still, the myths persist. 

In this article, we’re debunking the five most common myths about solar street lighting—using facts, field data, and design insights from more than 250,000 systems installed worldwide.

Myth #1: “Solar Street Lights Don’t Work in Cold or Cloudy Regions” 

The Misconception: 

Solar lighting only works in warm, sunny places—and fails in cloudy, cold, or winter-prone areas. 

The Truth: 

Modern solar lighting systems are engineered to perform year-round, even in challenging climates. Fonroche SmartLights use a proprietary energy management system—Power 365™—that stores multiple days of autonomy, so lights stay on even through extended periods of cloud cover, snow, or rain. 

Our engineering process begins with a 10-year climate and irradiance analysis, using industry-standard tools like Meteonorm and PVsyst. This ensures each system is sized to meet the specific solar and weather conditions of your project site—whether you’re in the Arizona desert or the upper Midwest. 

Fonroche systems have been successfully deployed in locations with harsh winters, frequent overcast days, and limited daylight hours—all while maintaining 365 nights of performance per year

It’s not about how sunny your city is—it’s about choosing a solar system designed for where you are.

Myth #2: “They’re Not Bright Enough for Roads or Sidewalks” 

The Misconception: 

Solar lights are too dim for roadway use and can’t match the brightness of grid-powered systems. 

The Truth: 

Fonroche solar street lights are engineered to meet—and often exceed—industry lighting standards for roadways, intersections, and pedestrian areas. 

Each SmartLight is equipped with high-output LED luminaires and optical configurations designed to optimize uniformity, distribution, and spacing. Unlike decorative or residential solar products, Fonroche’s solutions are built to satisfy IESNA and DOT requirements, making them suitable for everything from arterial streets to multi-use paths. 

In fact, solar lighting often outperforms grid-tied systems in uptime and consistency. While grid-powered lights are vulnerable to outages, copper theft, and maintenance lapses, Fonroche systems deliver 365 nights of uninterrupted lighting, regardless of external power conditions. 

So if you’re picturing a dim spotlight or garden-grade path light, it’s time to update that image. These are infrastructure-grade lighting systems, not accessories. 

Myth #3: “Solar Street Lights Are Only for Rural or Temporary Use” 

The Misconception: 

Solar lighting is fine for remote roads or short-term setups—but not suited for cities, urban upgrades, or long-term infrastructure. 

The Truth: 

That may have been true a decade ago—but today’s off-grid solar lighting systems are designed for permanent, high-performance use in dense environments. 

Fonroche SmartLights are currently deployed in major cities like Los Angeles, Vallejo, and Fort Worth, as well as dense tribal and federal facilities. These aren’t just fill-in fixtures—they’re serving as primary lighting in streetscapes, roundabouts, intersections, public housing zones, and park networks. 

What makes this possible? 

  • No trenching or utility connection required 
  • Install-ready in under an hour 
  • Smart controls and 10+ year battery life 
  • Dark-sky optics and aesthetic design options 

This is why solar is often the fastest, most cost-effective way to bring lighting to infill projects, underserved neighborhoods, or areas with overloaded grid infrastructure.

Myth #4: “They’re Too Expensive Upfront” 

The Misconception: 

Solar street lighting costs too much to install—and grid-tied systems are cheaper. 

The Truth: 

When you compare total costs—not just fixture price—solar almost always wins. 

Grid-tied lighting comes with hidden expenses: trenching, conduit, backfill, meter fees, transformers, permitting delays, and ongoing electricity bills. These add up fast—especially in dense or hard-to-access environments. Fonroche systems eliminate nearly all of those costs. 

Here’s the typical breakdown: 

Cost Factor Grid-Tied Solar (Fonroche) 
Trenching & Conduit Required Not needed 
Utility Permits & Delays Often significant None 
Transformer Upgrades Sometimes needed Not applicable 
Monthly Energy Bills Ongoing Zero 
Install Time Days to weeks ~45 minutes/light 
Copper Theft Risk High No exposed wiring 

And with Fonroche, maintenance is minimal. Our Power 365™ system and NiMH batteries are designed to operate for 10+ years without intervention, cutting future expenses even further. Upfront cost is only part of the story—solar saves more over time. 

Myth #5: “They Don’t Last Very Long” 

The Misconception: 

Solar street lights have short lifespans and need frequent maintenance or battery replacements. 

The Truth: 

Fonroche solar lighting systems are designed for 10–15 years of uninterrupted performance—with minimal maintenance and components that are engineered for durability, not disposability. 

Unlike legacy or low-cost systems that rely on lithium or lead-acid batteries, Fonroche uses NiMH battery packs that: 

  • Deliver consistent energy output over time 
  • Are 98% recyclable 
  • Operate reliably in high-heat, low-light, or cold conditions 
  • Require no annual servicing or mid-life replacement 

Additionally, each light is connected to Fonroche Connect, our real-time monitoring platform. This gives maintenance teams a live dashboard view of battery health, output, and performance alerts—before a light ever goes out

And because our systems are fully off-grid, there are no wires to steal, no underground cables to inspect, and no reliance on utility crews to fix outages. Reliability isn’t a feature—it’s the foundation.

Conclusion: Solar Street Lighting—Time to Rethink What’s Possible 

The myths surrounding solar street lighting don’t reflect today’s reality—they reflect outdated tech, cheap imports, or unfamiliarity with high-performance systems like Fonroche. 

With over 250,000 installations worldwide, Fonroche solar lights have proven themselves in harsh climates, dense cities, and long-term infrastructure plans. They’re not just an alternative to grid lighting—they’re a smarter, faster, and more sustainable solution

Whether you’re planning a new corridor, upgrading a park, or working within budget constraints, solar lighting isn’t something to fear—it’s something to evaluate with facts
